The mass number is a tally of the number of protons and the number of neutrons in an atom's nucleus. Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has.
Why does chlorine have 18 neutrons?
An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
What do CL 35 and CL 36 have in common?
They both have the same atomic number(proton number) as they are the same element, hence they also have the same number of electrons. Therefore, they have similar chemical properties, as the electrons determine the chemical property of an element.
